this question has answer here: click through transparent form 1 answer i want make form in delphi not handle mouse , keyboard events , pass them window below itself. how can this? you can make use of procedure blockinput of user32.dll you can try (with caution!): procedure bloqued(block:boolean); var milib: thandle; blockinput : function(block: bool): bool; stdcall; begin milib := getmodulehandle('user32.dll'); if milib <> 0 begin @blockinput := getprocaddress(milib, 'blockinput'); if @blockinput <> nil begin blockinput(block); end; end; end; procedure tform1.button1click(sender: tobject) ; begin bloqued(true); sleep(1000); bloqued(false); end; version without dinamic loading: function blockinput (block: bool): bool; stdcall; external 'user32.dll'; procedure tform1.button1click(...

let me start saying server administration experience limited, please forgive me if i'm making assumptions might seem odd. i've written extension google chrome , i'd test stability when left running continuously days, unfortunately have no access pc or laptop can leave on 24/7. idea set ec2 micro instance ubuntu, install ubuntu-desktop , vnc server, , connect via vnc instance, access graphical desktop interface, install google chrome, add extension , let run there. does sound feasible, or silly idea? potential limitations run into? aws gives complete control of os you're suggesting makes sense. the main disadvantages of running gui on network come down bandwidth , latency issues, might want consider getting ec2 instance close region possible. keep in mind aws security groups, need configured allow vnc connection. micro instances aren't made production use, may find it's not true test of typical system. should factor test may more appropriat...

looking behavior in this question , surprised see perl lstat() s every path matching glob pattern: $ mkdir dir $ touch dir/{foo,bar,baz}.txt $ strace -e trace=lstat perl -e 'say $^v; <dir/b*>' v5.10.1 lstat("dir/baz.txt", {st_mode=s_ifreg|0664, st_size=0, ...}) = 0 lstat("dir/bar.txt", {st_mode=s_ifreg|0664, st_size=0, ...}) = 0 i see same behavior on linux system glob(pattern) , <pattern> , , later versions of perl. my expectation globbing opendir/readdir under hood, , not need inspect actual pathnames searching. what purpose of lstat ? affect glob()s return? this strange behavior has been noticed before on perlmonks . turns out glob calls lstat support glob_mark flag, has effect that: each pathname directory matches pattern has slash appended. to find out whether directory entry refers subdir, need stat it. apparently done when flag not given.

i have model collection of tuple <string,string,string> public class patientdetails { public collection <tuple<string,string,string>> fieldvalidationrules { get; set; } } view stronglytyped i.e patientdetails accessed in cshtml @model now want assign fieldvalidationrules object javascript variable can refer client validations per rules specified in collection. have following line of code: $(document).ready(function(){ _jsfieldvalidationrules = "@model.fieldvalidationrules"; }); but have problem here _jsfieldvalidationrules doesn't assigned values in "@model.fieldvalidationrules instead gets assigned to: system.collections.objectmodel.collection 1[system.tuple3[system.string,system.string,system.string]] what do make work. what do make work. use json serializer: $(document).ready(function() { _jsfieldvalidationrules = @html.raw(json.encode(model.fieldvalidationrules)); });
